Charitynavigator.org’s Good Cards work like gift certificates: You pick the donation amount, but your recipient selects the charity.

HELP CHILDREN

At shop.stjude.org, buy a toy, pet treats or clothes―and all profits benefit the St. Jude Children’s Research Hospital. Also check out the shop at unicefusa.org, where purchases benefit kids around the world.

PAMPER HER

Select “Shop for a Cause” on philosophy.com and find items like shower gel and bubble bath starting at $15. All net proceeds go to charity.

SHOP FOR GOOD

From flowers to food, giftback.com peddles dozens of great presents. When you make a purchase, the charity of your choice receives 10 percent of the sale price.

SEND AN ECO-FRIENDLY E-CARD

With every e-card you buy at treegreetings.com, a tree is planted in the United States or Central America. Cards start at $9, and recipients receive a personalized planting certificate.

MAIL RETURNABLE CARDS

Let recipients feel good, too, with cards they can send back to be recycled. Check out reproduct.net.
